Judgement and Evidence
We make such big judgements based on so little evidence. All the time. Most often we do this about other people, but we also do it about situations. We hear a couple sentences about someone or a situation and make a broad judgment on it. Learning to reserve judgement until we have all the facts is a sign of maturity. It also helps us and others. When we reserve judgement we don't write people and things off so soon. So we end up having more higher quality options and opportunities.
